(2104 Benoit Place, Gretna, La. 70053), and Fritz G. Kerrinnes, Jefferson Parish, La. (Rte. 1, Box 743, Slidell, La. 70458) Filed July 5, 1968, Ser. No. 742,860 Int. Cl. B65d 47/20 US. Cl. 222511 1 Claim ABSTRACT OF THE DISCLOSURE A snap-on cover for a shaker, said cover having holes and a slide having holes slidably mounted in said cover and adapted to slide for said holes to register in one slide position, and a spring transversely mounted between said cover and slide to bias said slide to a position for the holes to be out of register, said spring being wholly contained in said cover.

This invention is a shaker which can be used indoors or outdoors. It can be used by hunters, fishermen or campers as it remains automatically closed at all times. It can also be used by housewives and mothers for such things as flour, salt, pepper, sugar, foot powder, baby powder, etc.

This invention can be made of transparent or any other suitable material. The shape can be round, oval or right angular, etc. This invention has a snap on cover with a leaf spring and seal plate.

The main purpose of this invention is to provide a shaker which is completely spillproof and at the same time provides better protection against moisture, which in course, prevents spoilage and is more economical.

This invention provides a shaker which can be mass produced and will be of low cost because of its simple construction.

More advantages, benefits and objects of this invention will be evident from the following detailed description, taken in conjunction with the accompanying drawing, in which:

FIGURE 1 is a top view if the shaker, in this case an oval form.

FIGURE 2 is a cross sectional view taken along line AA of FIG. 1.

FIGURE 3 is a cross sectional view taken along line BB of FIG. 2 to show slide and leaf spring installation and function.

As seen in the drawing this shaker is made of (5) five parts, which are: 1, cover; 2, slide; 3, seal plate; 4, leafspring; 5, container.

The cover is made to'snap onto container 5 and contains rows of holes. These holes are made in different diameters to suit the contents which are used in the shaker.

In the cover 1 is installed a slide 2 which has similar rows of holes as the cover 1. This slide 2 is pressed to the right rand side as illustrated in FIGURE 2 and FIGURE 3 by leafspring 4. Only when slide is pressed to the left are holes open and contents can escape.

Tension of leaf spring shall be so as to prevent small children from opening the shaker.

3,506,168 Patented Apr. 14, 1970 ICC Leaf spring is held in place by a slot in cover 1, and is held in this slot by seal plate 3.

Seal plate 3 contains one large hole and fits snugly in cover 1. The purpose of seal plate 3 is mainly to prevent contents from coming between cover 1 and slide 2 and also to seal oli contents from spilling through slide actuator end.

Having thus completely described the invention which We claim is new, we desire to be protected by Letters Patent of the United States.

What is claimed is:

1. In combination, a shaker having an open ended hollow container for receiving and dispensing hydroscopic and moisture damageable granular materials, and a cover adapted to snap over the open end of said container, said cover comprising: an outer cover having inner and outer surfaces and a plurality of perforations and defining on its inner surface a slot radially extending from its periphery to beyond its center, and a shorter narrower segmentally extending slot normal to said radially extending slot and radially spaced from its interior end, said outer cover having a depending peripheral flange adapted to snap over the open end of said container; a flat slide plate having inner and outer ends and adapted to slidably fit, inner end first, into said radially extending slot defined in said outer cover, said slide plate having an area perforated similarly to said outer cover and adapted to slidably register the said perforations in one slide position of said slide plate, and said slide plate outer end extending beyond the periphery of said outer cover; and are shaped leaf spring have oppositely disposed ends and adapted to be mounted in said segmentally extending slot of said outer cover and intermediate its said ends which engage the inner end of said slide plate to bias the slide plate outwardly and its perforations out of registration with those of the outer cover; and a flat seal plate secured to the inner surface of the outer cover for retaining said spring and slide plate plate in their respective slots and operating positions and defining a hole positioned under and extending below the perforated area of said outer cover for sealing the open end of the hollow container extending beyond the perforated area of the outer cover and the spring situated in said non-perforated area, whereby the hydroscopically and moisture damageable materials are sealed from all contact with the air and the spring, but when the outer end of the slide plate is manually operated against the bias of the spring the contents of the container can readily be shaken from the shaker.
